The present invention relates to improvements in cartridges, more particularly to shot cartridges for breech loading guns. Y

According to the present invention, 'the 5 charge of shot is held within a cup or shell which may be formed of paper, parchment, l

papier-mch, buckram or the like material, but is preferably however, made of corrugated metal foil which has great strength 1,0 with little weight. This cup is secured on its base by gluing, riveting or by means of a wire, pin or headed staple to the usual wad Vof felt, cork or the like.

The invention is more particularly described with reference to the accompanying drawing in which n y Figure 1 is a sectional elevation through a sporting cartridge according to this invention. 9

on the line A.`B. of Figure 1.

Figure 3 is a sectional elevation of a modi: f lied form of cartridge.

Figure 4 is a sectional view on the line C. D. of Figure 1.

The sporting cartridge of the present invention consists of a cardboard shell 1 attached in the usual manner to a metal end 2 having the usual'per'cussion cap 3 and charge of powder 4f.

According to this invention, shot 5 are held Within a cup or shell 6 formed of corrugated metal foil, paper parchment, papiermch, buckram or the like` material, the corrugations preferably being spirally disposed as shown. If desired, the outer surface of the corrugations may be lled up y with plastic material 7, such .as stearine, tal- Vlow, or the like material to present a smooth upper surface, thereby enabling this container 6 for the shot 5 to form a gas-tight piston along the barrel of vthe gun, in its motion, and to serve to lubricate -its passage.

stance, by means of a wire pin clip 10 having a shank l1 stapled into the wad 9.

This construction shows a modified meth-l od of securing the corrugated metal foil shell 6 to the wad by means for instance,`of a two-armed rivet 14. y I declare that what I claim is 1. A sporting cartridge comprising in combination anv outer container, a percussion cap, a wad,vloose shot, a spiral corrugated metal foil shell containing said shot and mens to vsecure said shell directly upon said wa 2. A sporting cartridge comprising in combination an outer container,'a percussion cap, a wad, loose shot, a light corrugated shell containing said shot, and means to-secure said shell directly upon said wad, and a solid lubricant completing the cylindrical externa V contourof said corrugated shell. l
